# 3.1.1(a) Link to Other Purchase Methods

3.1.1(a) Link to Other Purchase Methods: Developers may apply for entitlements to provide a link in their app to a website the developer owns or maintains responsibility for in order to purchase digital content or services.

## Overview

**3.1.1(a) Link to Other Purchase Methods:** Developers may apply for entitlements to provide a link in their app to a website the developer owns or maintains responsibility for in order to purchase digital content or services. These entitlements are not required for developers to include buttons, external links, or other calls to action in their United States storefront apps. Please see additional details below.

- StoreKit External Purchase Link Entitlements: apps on the App Store in specific regions may offer in-app purchases and also use a StoreKit External Purchase Link Entitlement to include a link to the developer’s website that informs users of other ways to purchase digital goods or services. Learn more about these [entitlements](https://developer.apple.com/documentation/storekit/external_purchase). In accordance with the entitlement agreements, the link may inform users about where and how to purchase those in-app purchase items, and the fact that such items may be available for a comparatively lower price. The entitlements are limited to use only in the iOS or iPadOS App Store in specific storefronts. In all other storefronts, except for the United States storefront, where this prohibition does not apply, apps and their metadata may not include buttons, external links, or other calls to action that direct customers to purchasing mechanisms other than in-app purchase.

- Music Streaming Services Entitlements: music streaming apps in specific regions can use Music Streaming Services Entitlements to include a link (which may take the form of a buy button) to the developer’s website that informs users of other ways to purchase digital music content or services. These entitlements also permit music streaming app developers to invite users to provide their email address for the express purpose of sending them a link to the developer’s website to purchase digital music content or services. Learn more about these [entitlements](https://developer.apple.com/documentation/storekit/external_purchase). In accordance with the entitlement agreements, the link may inform users about where and how to purchase those in-app purchase items, and the price of such items. The entitlements are limited to use only in the iOS or iPadOS App Store in specific storefronts. In all other storefronts, streaming music apps and their metadata may not include buttons, external links, or other calls to action that direct customers to purchasing mechanisms other than in-app purchase.

- If your app engages in misleading marketing practices, scams, or fraud in relation to the entitlement, your app will be removed from the App Store and you may be removed from the Apple Developer Program.
